  • High tension drumhead
    Patent number: 4754683
    Abstract: The material constituting a drumming surface is anchored at its perimeter with epoxy to a supporting hoop. Between the hoop and tightening means there is located an O-ring of tension increasing material. When the tightening means is urged downwardly to increase the tension on the drumming surface, the tension increasing material distorts, partly laterally, thereby creating a tension which substantially increases the relative tension of the drumming surface material.
